From WordNet (r) 2.0 [wn]:

  subroutine
       n : a set sequence of steps, part of larger computer program
           [syn: {routine}, {subprogram}, {procedure}, {function}]

From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:



  subroutine
       
           (Or "procedure") A sequence of {instructions}
          for performing a particular task.  Most programming languages,
          including most {machine languages}, allow the programmer to
          define subroutines.  This allows the subroutine code to be
          called from multiple places, even from within itself (in which
          case it is called {recursive}).  The programming language
          implementation takes care of returning control to (just after)
          the calling location, usually with the support of call and
          return instructions at {machine language} level.
       
          Most languages also allow {arguments} to be passed to the
          subroutine, and one, or occasionally more, {return values} to
          be passed back.
       
          A {function} is often very similar to a subroutine, the main
          difference being that it is called chiefly for its return
          value, rather than for any {side effects}.
